I'm sorry, I didn't see your definition of "policy" here. Are you
talking about a written policy, a technically implemented policy, or a
password strength meter?

A written policy, just like a technical policy implementation, can be
written and configured so that it specifically rejects 123456, and
nothing else.

I wouldn't be surprised if the smarter guys in here could develop a
password strength meter (or "filter", if you prefer) that would block
123456 and guarantee you nothing else would be blocked.

Personally I prefer thinking of a policy as a description of a desired
state, and NOT as law or rules that you MUST at all times be 100%
compliant with.
